Allow more light to enter the living room area by using light curtains. Instead of using heavy looking "valances" use basic and if possible semi transparent curtains that are only enough to reduce glare that may be caused because of direct sunlight. Use brighter color schemes commonly known as "hot" color schemes. These create a very good reflection and transmission of natural as well as artificial light inside the living room. You can find one more different procedure for defining the thought of the living room (or any interior space) and that's the empty volume put aside after all the furniture as well as other accessories have been fitted. Because anything in this living world is often "relative". The perceived volume is always relative to the empty volume that is normally used for circulation. The more empty volume you get, the bigger the room will look.
